Brendan Rodgers has insisted he is "very confident" Celtic will bolster their frontline before the end of the summer transfer window.
The Parkhead boss is keen to add to his attacking options before the window closes after the departure of Nicolas Kuhn and Luis Palma added to Kyogo Furuhashi's exit last season.
Rodgers currently has Adam Idah, Shin Yamada, Callum Osmand and Johnny Kenny as striker options.
Celtic will be without Jota until into the new year with James Forrest, Benjamin Nygren, Yang and Daizen Maeda as wingers available for selection.
“We still have some work to do,” said Rodgers.
“I think the players that we have in the building have been very, very good in this pre-season so far.
"But like I say, we still have work to do in the market.
“I think it’s very clear where our gaps are - in our front line, where we need support.
“I’m very confident that we’ll be able to do that before the market finishes.”

"We’ve still got a lot of work to do," said Rodgers of transfer business after the win over Newcastle at the weekend. "But the guys that are training and working with us are doing so well.
"You saw that today, and they're all developing their fitness and participating in the games for us.
"I would expect us by the end of the window to have brought in players in certain areas of the pitch that we need to go through a really long season.
"But it's an exciting season for us."
